Foam & Sponge Gasket Materials

Sealing, cushioning, and weather barriers.

Foam and sponge gasket materials seal where rigid gaskets cannot. These soft, compressible cellular elastomers and foams conform to uneven surfaces, fill wide tolerance gaps, and seal under light closure force, which makes them the right choice for low-pressure sealing, vibration and shock damping, dust and weather barriers, sound dampening, and thermal insulation. Closed-cell sponge and foam resist water, air, and moisture intrusion for environmental gasketing, while open-cell grades compress easily for cushioning, padding, and air filtration. Grades like Poron and Volara add long-term compression recovery and crosslinked durability for demanding sealing and cushioning duty.

Cannon Gasket custom die-cuts foam and sponge gaskets to your drawing in neoprene, EPDM, silicone, polyurethane, PVC, EVA, and specialty cellular materials, in soft, medium, and firm densities. We supply pressure-sensitive adhesive (PSA) backing on one or both sides for fast peel-and-stick assembly, plus material blends, tight tolerances, kiss-cutting, and short or long production runs from our ISO 9001 facility in Fontana, California. From prototype through production, we cut the right cell structure and durometer for your seal and finish it ready to install.

Materials

Foam and sponge gasket materials we die-cut.

Open- and closed-cell sponge plus structural foam grades, each matched to a sealing, cushioning, or insulation niche and available with PSA backing.

Neoprene Sponge
Closed-cell neoprene sponge with balanced oil, weather, and flame resistance for low-pressure environmental and weather-barrier sealing.
EPDM Sponge
Closed-cell EPDM sponge with outstanding ozone, UV, and water resistance for outdoor and weatherstrip sealing.
Silicone Foam
Wide-temperature silicone foam for high-heat gasketing, flame-resistant enclosures, and resilient compression sealing.
Polyurethane Foam
Versatile open- or closed-cell polyurethane foam for cushioning, gap filling, and vibration damping.
Closed-Cell Sponge
Sealed-cell structure that blocks water, air, and moisture for environmental and weather-resistant gaskets.
Open-Cell Sponge
Soft, breathable cell structure for cushioning, padding, sound absorption, and air filtration.
Poron®
Microcellular polyurethane with excellent compression-set resistance for long-life cushioning and consistent gasket seals.
Volara®
Crosslinked closed-cell polyethylene foam offering a clean, durable surface for cushioning, padding, and gasket sealing.
PVC Foam
Closed-cell PVC foam for cost-effective dust, moisture, and weather sealing in low-pressure applications.
EVA Foam
Flexible closed-cell EVA foam for shock absorption, cushioning, and lightweight gasket and padding seals.

Frequently Asked Questions

Common questions about custom gaskets.

Are you ISO 9001 certified?
Yes, ISO 9001:2015 certified. Documented quality management covers incoming material verification, in-process inspection, calibrated measurement, final inspection, non-conformance handling, corrective action, and full lot traceability. AS9100-ready for aerospace, with MIL-spec and FDA 21 CFR 177.2600 / USP Class VI grades available on request.
Can you cut custom gasket profiles?
Yes. Custom steel-rule and rotary tooling is built in-house from your drawing or DXF. Complex profiles, multiple through-cuts, tight bolt patterns, and irregular perimeters are all standard work.
Can you supply PSA-backed gaskets?
Yes. Pressure-sensitive adhesive backing is a standard option on most rubber and fiber gasketing, with either permanent or removable liners. Kiss-cut on liner and through-cut both supported on flatbed and rotary presses.
What tolerances can you hold on gasket dimensions?
Standard die-cut tolerance is ±0.010 to ±0.015 inch on OD and ID, depending on material durometer and thickness. Tighter tolerances are available on select grades and thicknesses. Ask if your drawing specifies something tighter and we will confirm feasibility during the quote.
Which gasket material is right for my application?
Start with temperature range, fluid contact, and regulatory requirements. Buna-N is the default for oil and fuel. EPDM for weather, water, and steam. Silicone for extreme temperature and FDA grades. Viton for aggressive chemicals. Our gasket material selection guide walks through the decision framework.
How fast do you return a quote?
Most RFQs come back within one business day. Simple profile updates to an existing tool quote same-day. Send a drawing, DXF, or competing part number and our engineering team reviews material, tolerance, and volume before pricing.
What is the minimum order quantity?
Minimums depend on the part and material. We cut prototype and first-article quantities for engineering evaluation, then scale up to production volumes from the same tooling. For high-volume programs we run JIT, VMI, and Kanban replenishment out of Fontana, California.
What should I send with an RFQ?
Ideal: a drawing or DXF, material spec (or compound family), estimated annual volume, and any regulatory callouts (FDA, USP Class VI, AS9100, MIL-spec). If you only have a sample or a part number from a competing supplier, send that and we will reverse-engineer the spec before quoting.
What are typical lead times?
Prototype and first-article parts usually ship in 5-10 business days. Production runs from existing tooling are 2-3 weeks depending on volume and material lead time. Rush and expedite options available on a case-by-case basis.
